Re: Digital Foundry - CRT better then 4K OLED

look for a number that ends in "kHz". generally, larger crt's have higher hsync rates. phosphor ghosting doesn't depend on tube age. i'm not sure if it's possible to determine the tube condition before buying a monitor (other than asking the seller how much it's been used... which he might not even ...

Re: Digital Foundry - CRT better then 4K OLED

age/condition of tube is more important than the specific model aside from that, the most important metric is the max hsync rate. look for something >100kHz, this determines the maximum product of (vertical resolution)*(refresh rate) aperture grill (sony trinitron mitsubishi diamondtron or rebrands)...

Re: Digital Foundry - CRT better then 4K OLED

ya crt's have a film with an antireflective coating (https://en.wikipedia.org/wiki/Anti-reflective_coating). (totally different from the antiglare on most lcd's). it's similar to the coating on eyeglasses.

if you look a specular reflection from a crt, it will appear blue because of this.

Re: Digital Foundry - CRT better then 4K OLED

well like crt's are great and all but for purely testing purposes, i don't see the benefit of specifically using a top of the line crt. like all crt's have 0 input lag persistence/motion blur for crt's doesn't depend on refresh rate in any way some crt's might have shorter persistence phosphors but ...

Re: Digital Foundry - CRT better then 4K OLED

it's all battery powered. no switching noise.

the periodic pattern is from picking up radiation from the crt

Re: Digital Foundry - CRT better then 4K OLED

yup it's still working perfectly https://i.imgur.com/uzXvc8R.jpg covered in a box to shield some radiation that it's picking up from the crt (the wiggles every 12us). not perfect but helps somewhat https://i.imgur.com/wzkbmKQ.jpg this is the response to 5 (white) pixels. video bandwidth is 146.88MHz...

guess i'll recreate it tonight... hopefully my photodiode setup still works

Re: Digital Foundry - CRT better then 4K OLED

i can't figure out what scanskew is doing; i'm not too interested at the moment. of course it's easy to see the lag of the cursor: use a noncompositing window manager (i.e. such that dragging windows around has tearing) and see how the cursor can lag behind objects you drag around but if you're not ...

Re: Digital Foundry - CRT better then 4K OLED

i don't mean when dragging something around, but just like the motion of a cursor by itself.

crt phosphors aren't charcterized by a single timescale for decay.
but anyway, as a point of reference, on fw900 i can easily see 1 pixel details on testufo for the ufo moving at 960px/s
